PHP and MongoDB Web Development Beginner's Guide

Overview of this book

With the rise of Web 2.0, the need for a highly scalable database, capable of storing diverse user-generated content is increasing. MongoDB, an open-source, non-relational database has stepped up to meet this demand and is being used in some of the most popular websites in the world. MongoDB is one of the NoSQL databases which is gaining popularity for developing PHP Web 2.0 applications.PHP and MongoDB Web Development Beginner’s Guide is a fast-paced, hands-on guide to get started with web application development using PHP and MongoDB. The book follows a “Code first, explain later” approach, using practical examples in PHP to demonstrate unique features of MongoDB. It does not overwhelm you with information (or starve you of it), but gives you enough to get a solid practical grasp on the concepts.The book starts by introducing the underlying concepts of MongoDB. Each chapter contains practical examples in PHP that teache specific features of the database.The book teaches you to build a blogging application, handle user sessions and authentication, and perform aggregation with MapReduce. You will learn unique MongoDB features and solve interesting problems like real-time analytics, location-aware web apps etc. You will be guided to use MongoDB alongside MySQL to build a diverse data back-end. With its concise coverage of concepts and numerous practical examples, PHP and MongoDB Web Development Beginner’s Guide is the right choice for the PHP developer to get started with learning MongoDB.

Preface

Chapter 8. Building Location-aware Web Applications with MongoDB and PHP

Location-aware websites are one of the hottest trends in the present day web development scenario. A location-aware web application takes the user's geographic location as an input, and renders output to that user (or provides some sort of service to him) based on his location. Take Foursquare for example, a hugely popular social networking website that lets you "explore" interesting venues around your location, gives you badges when you "check in" at a venue, shows where your friends are checking in, and so on. Applications like this require databases that have special capabilities for storing, querying, and comparing geographic position parameters (latitude, longitude, and so on). MongoDB has Geospatial Indexing, which makes it efficiently perform location-based queries. In this chapter, we are going to work with geospatial indexing and learn how to use it to develop location-aware applications with PHP.
